Experiment Writing

This week
for our writing

WALT
create and write an experiment

We
will:

-work
together

-add
detail for anyone to use

-show our vision

To do this we will write
a plan in our science inquiry groups. Then we will work individually on our
experiment writing. At the end of the week we will put our work together in our
groups and publish it onto our group google doc. Then we will be very prepared
to start our experiment!

It might look a little
something like this when we are finished…

Group
inquiry experiment

Scientists:

Sophie and Kelly

Question:

Does the amount of water we feed plant effect the growth?

Hypothesis:

We think the more water we give the plants, the more it will grow.

List of Materials:

2 seeds, 2 pots, water, measuring cup, ruler, soil

Experiment:

We are going to plant 2 seeds and feed them different amounts of water
to see which plant grows taller and healthier

Method

1.Half fill each pot with soil

2.Put
1 seed in each put of soil and then cover with more soil to the top of the
pot

3.Place
pot next to each other on a sunny windowsill

4.Label
1 pot “Control” and the other pot “Experiment”

5.Feed
each pot ¼ cup of water

6.Feed
Control pot ¼ cup of water every second day. Feed Experiment pot ¼ cup of
water for breakfast, lunch and dinner every day.

7.After
three weeks of this watering routine, measure the plants growth and compare
the health between them by looking at the colour and strength of the plant.

Results:

After 3 weeks of watering these plants, the Control plant grew
10cm and was green and healthy. The Experiment plant grew only 6cm and then
began to wilt and turn yellow. After doing some research about why this
happened, we found out that it is not healthy to feed plants such a large
amount of water. Too much water is not good for them and they actually end up
drowning. We found out that plants breathe through their roots and by feeding
them too much water, the plants couldn’t take in the oxygen.

Conclusion:In
conclusion the outcome of the experiment was opposite to our hypothesis. It
is not good to over-water a plant and it does not help the plant grow enormous.

And here is a fun song about plants we
are learning
